Capillary microcuvette having double loading means

Abstract

The present invention relates to a capillary microcuvette, the microcuvette comprises a body member having two plates and a cavity formed within the body, the cavity being defined by two opposing inner surfaces of the two plates of the body member, a portion of the cavity defining a detection zone, a capillary inlet being provided at one end of the body member that is communicated with the cavity, a sample slot being provided at a portion of the body member in which the capillary inlet is not formed, the sample slot being communicated with the cavity. The present microcuvette improves user convenience by providing dual application means of applying a specimen directly from a fingertip or using a pipette.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a national phase application International Patent Application No. PCT / KR2012 / 006465, filed on Aug. 14, 2012, which claims the benefit of Korean Patent Application No. 10-2011-0080964, filed Aug. 16, 2011, in the Korean Intellectual Property Office, the disclosure of which are incorporated herein.TECHNICAL FIELD[0002]The present invention generally relates to a microcuvette, and more particularly, to a microcuvette having dual sampling means by which direct application of a specimen into the microcuvette or injection of a specimen into the microcuvette using a pipette is possible.BACKGROUND[0003]Generally capillary microcuvettes are used to perform an optical analysis on the liquid specimen which has been processed in a separate reaction with a proper reagent after it being collected, or to perform an optical analysis on the specimen directly after the collection.[0004]For example, the conventional capillary microcuvett...

AI Technical Summary

Benefits of technology

The present invention is a microcuvette that improves the user's convenience and accuracy of measuring by providing two ways to apply blood samples: directly from finger tips or using a pipette from a collection tube. This allows for easier and more flexible application of samples. Additionally, the microcuvette allows for any amount of sample to be loaded as long as it fills the cavity by capillary action. These features make the microcuvette more user-friendly and efficient for measuring samples.

Problems solved by technology

However, the problem with the conventional microcuvette is that it can apply the blood specimen only through the sample inlet formed therein.

This has resulted in the inconvenience that a finger of the subject needs to be aligned with the narrow sample inlet to apply blood to the microcuvette.

The conventional microcuvette is particularly inconvenient because the capillary force to introduce the sample into the detection zone is only generated at a restricted area of the narrow sample inlet.

Further, the conventional microcuvette as described above becomes more difficult to use with blood samples collected beforehand and kept in a tube.

However the conventional microcuvette has a structure that is not very much compatible with the micropipettes.

However, the former extra procedure as described above may cause biohazardous problems if a blood sample is spilled out during the process.

The latter, though it removes a risk of blood spills, may also cause a contamination problem during the process.
